This study introduces a real-time method to detect feedback error-related potentials (f-ERPs), crucial for learning and rehabilitation. The system shows stable performance, suggesting potential for personalized therapeutic interventions.

Area of Science:

Neuroscience
Rehabilitation Medicine
Cognitive Science

Background:

Feedback error-related potentials (f-ERPs) are linked to human learning and are relevant for rehabilitation strategies.
Therapeutic interventions often utilize feedback stimuli, making f-ERPs a potential tool to enhance patient progress.

Purpose of the Study:

To develop and validate a method for real-time identification of feedback evoked potentials.
To assess the performance and stability of this detection method over time.

Main Methods:

A novel system was designed to detect feedback evoked potentials in real-time during a time-estimation task.
The system was tested on five participants across two sessions separated by three weeks.

Main Results:

The system achieved a mean single-trial detection performance of 71.62% for real-time recognition.
Offline classification yielded a higher performance of 78.08%.
Analysis indicated stable feedback responses between testing days, reducing the need for repeated user training.

Conclusions:

The proposed method effectively identifies feedback evoked potentials in real-time.
The stability of f-ERPs suggests their utility in personalized and adaptive rehabilitation without extensive retraining.
